Dynamic Root of Trust in Trusted Computing

In this paper we introduce basic knowledge of Trusted Computing briefly. And then, we describe attack towards trusted computing system, and also discuss vulnerability of modern trusted computing system. We will exam two solutions, which can be named under using ’dynamic root of trust’, for these problems. Generally, it will change the ’old’ architecture of ’static root of trust’-based trusted computing system by leveraging new feature provided by new chips of AMD and Intel. We also summary these solutions with a discussion of their benefits and drawbacks compare with formal methods. Finally, for the drawbacks, we propose some methods to im-
